On upper estimates for approximation numbers of a Laplace type transformation
Elena P. Ushakova
We deal with a real valued integral operator L of Laplace transformation type acting between Lebesgue spaces on the semi-axis. Sufficient conditions for belonging L to Schatten typ…

On compactness of Laplace and Stieltjes type transformations in Lebesgue spaces
Elena P. Ushakova
We obtain criteria for integral transformations of Laplace and Stieltjes type to be compact on Lebesgue spaces of real functions on the semiaxis.
